How to secure a sidemount 2nd stage

Traditionally when technical diving the long hose is secured using a P-clip secured close the 2nd stage, ideally using cave/DSMB line. The requirement for a quick release or breakaway tying method was not required because the diver was breathing the long hose (not to be confused with the need of cutting the line if the clip is jammed when the regulator is secured to a D-ring)

However when diving either independent twinset or sidemount cylinders the diver is breathing either the left (short hose on a bungee necklace) or right (long hose hoglooped with a P-clip) cylinders. Breathing the long hose is no issue – hand off the regulator as taught and switch to the backup (short hose) on your necklace.
Therefore when breathing the short hose the long hose regulator is clipped of to the right shoulder D-ring. It must be secured with a breakaway clip as an Out Of Air (OOA) diver could grab the regulator which must come free from the securing method.

A New (alternitive) way

This method of securing the 2nd stage long hose regulator can be adapted to suit all designs of regulator .
